[Javascript] required entry field

Fri Mar 28 16:04:03 CST 2003

No need for stabs, we are all exchanging experience between this memberhood. 
The question was addresed to Rodney as he sugested other way of salving the 
guy's problem.

I don't see no need to call the form collection in order to access a single 
field. Why ask browser to count items of collection once again
when you can directly and selectively retrieve its properties.

Scripters should avoid using calls like 'document.all', allways and 
regularly. Give some considerations in optimizing their scripts, the speed 
of execution, size of the script, removing all the comments, using short 
declarations, variable names, shorter object calls and other, to achieve 
faster downloads, and faster executions.

Though this prism,it's contraproductive calling collections of any kind when 
items have given Names or IDs.

Regards!
